Well first, if Mike Pence nominated him, he is almost surely a good candidate! Mile Pence is a good conservative and has demonstrated such in the past. If he is giving his allegiance, then he should be listened to.
Two, it does not matter who anyone nominates or supports...as long as they a a decent Conservative, they will be accepted.
At that point it is for the voter to decide...
All the “conventional wisdom” went out the window in this election cycle.
